A black hairy tongue is caused by too much bacteria or yeast growth in the mouth: the bacteria build up on tiny rounded projections called papillae. These lie along the surface of the tongue. Instead of shedding as they normally do, the papillae start to grow and lengthen, creating hair-like projections.
There are a number of causes for black tongue. It can be caused by an overgrowth of fungi or bacteria in the mouth, in which case drugs may be needed to limit the growth, and it has been linked with a number of medications, including antibiotics and drugs that contain bismuth.
